Abstract
Background Lipids and lipoproteins are significantly involved in maintaining structural and functional components of the human brain and neurons, but their role in the development of Alzheimer's disease (AD) and vascular dementia (VD) remains unclear. Objective The aim of the present study was to explore the differences in the standard and novel lipid profile parameters in patients with AD and VD, stratified by the degree of cognitive impairment (CI). Methods Present study included 66 patients with AD, 50 patients with VD, and 60 control subjects. For an evaluation of the global cognitive function the Montreal Cognitive Assessment (MoCA) test was used. In order to distinguish patients with VD from those with AD the Hachinski ischemic score was used. Plasma total cholesterol (TC), high-density lipoprotein -cholesterol (HDL-C), and triglycerides (TG) levels were determined using standard enzymatic colorimetric techniques, whereas the Friedewald formula was used to calculate low-density lipoprotein-cholesterol (LDL-C) levels. The non-traditional lipid indices such as TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratio were separately calculated. The differences between the groups were analyzed with the Kruskal Wallis test followed by the Mann-Whitney test or with ANOVA followed by the Tuckey posthoc test. Results Results of the conducted study have found that the patients in AD group with moderate CI and patients in AD group with severe CI exhibited significantly lower levels of serum TC, TG, LDL-C, VLDL-C, Non- HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C and LDL-C/HDL-C compared to cognitively normal control subjects. Moreover, patients in VD group with severe and moderate CI had significantly lower level of TG compared to control group of subjects. Our results have also shown that patients in AD group with moderate CI had significantly lower level of TC, TG, LDL-C, Non-HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C compared to VD patients with moderate CI. In addition, patients in AD group with severe CI had significantly lower level of TC, LDL-C, Non-HDL-C and TC/HDL-C compared to VD patients with severe CI. Conclusion The results of this study have shown dysregulation of lipid metabolism in AD and VD patients with different degree of CI. In both moderate and in severe CI, patients with AD had lower levels of majority of standard and novel lipid parameters compared to patients with VD. Further larger prospective studies are required to elucidate the accuracy of standard and novel lipid parameters in the assessment of different degree of CI in AD and VD.

Abstract
Background: Conflicting data exist on traditional lipid profiles in patients with Alzheimer’s disease (AD) and vascular dementia (VD), whereas scarce number of studies evaluated non-traditional lipid profiles in patients with AD and VD. Studies have shown that ethnic background may affect lipid profile. Objective: The aim of the present study was to conduct comparative assessment of traditional and non-traditional lipid profiles in Bosnian patients with AD and VD. Methods: A controlled, cross-sectional study was performed with 66 patients with AD, 50 patients with VD, and 60 control subjects. The Montreal Cognitive Assessment (MoCA) test was used for an evaluation of the global cognitive function. The Hachinski ischemic score was used to distinguish patients with VD from those with AD. Plasma total cholesterol (TC), high-density lipoprotein -cholesterol (HDL-C), and triglycerides (TG) levels were determined using standard enzymatic colorimetric techniques, whereas the Friedewald formula was used to calculate low-density lipoprotein-cholesterol (LDL-C) levels. The non-traditional lipid indices such as TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratio were separately calculated. The differences between the groups were analyzed with ANOVA followed by the Tuckey posthoc test or with the Kruskal Wallis test followed by the Mann-Whitney test. Results: Results of the present study have shown that patients in AD group had significantly lower level of TC, TG, LDL-C, VLDL-C, Non-HDL-C and significantly lower atherogenic index compared to the control group (CG) and compared to the VD patients. Significant difference in values of TG and VLDL-C was observed between VD and the CG, whereas no significant difference in values of TC, LDL-C, atherogenic index and Non-HDL-C was observed between these two groups. Our results have also shown that TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratios were significantly lower in AD patients compared to the VD and CG. Moreover, TG/HDL-C ratio was significantly lower in VD compared to the CG. However, a significant difference in TC/HDL-C and LDL-C/HDL-C was not observed between VD and the CG. Conclusion: Based on the results of the present study it can be deduced that there is a difference in traditional and non-traditional lipid profiles between AD and VD patients of Bosnian descent. Obtained results suggest that lipids are decreased in AD and in VD to a certain extent. However, since there is an inconsistence in literature whether there is an association between cholesterol and cognition, large prospective studies are required to elucidate this controversy.

Abstract
INTRODUCTION Acute appendicitis (AA) is the most common surgical condition of the abdomen in children. The aim of this study was to analyse the possible use of the neutrophil-to-lymphocyte ratio (NLR) in the diagnosis and prediction of AA complications in children. MATERIAL AND METHODS We included 170 AA patients under 15 years of age, who were divided into the following groups: Group 1 - non-operated patients with AA, and Group 2 - patients who underwent appendectomy. Based on pathologic grades of AA, Group 2 was subdivided into: Group A - phlegmonous, Group B - gangrenous, and Group C - perforated AA. NLR was calculated as the absolute neutrophil count divided by the absolute lymphocyte count. RESULTS In Group 2 NLR was significantly higher than in Group 1 (5.5 (1.9-9.9) vs. 2.3 (1.2-3.7); p < 0.001). A significant difference in NLR was found between Group C and Group A (p < 0.001), and as well as between Group B and Group A (p = 0.001). The determined optimal cut-off value of NLR in differentiating Group 1 vs. Group 2 was ≥ 3.48 (p < 0.001). In differentiating Group A from Group C the optimal cut-off value of NLR was ≥ 5.61 (p < 0.001). Furthermore, optimal cut-off value of NLR in differentiating Group A from Group B was ≥ 5.45 (p = 0.001). CONCLUSIONS The obtained results suggest that NLR could be used as a simple and reliable test in the diagnosis and prediction of AA complications in children. However, to draw definite conclusions on the predictive power of NLR as a marker of AA large multicentric studies are required.

Abstract
BACKGROUND Cerebrospinal levels of isoprostanes (IsoPs) have been established as biomarkers of oxidative stress in Alzheimer's disease (AD) and vascular dementia (VD). The value of peripheral levels in the diagnostics of these diseases is less conclusive. The aim of this study was to determine serum 8-iso-prostaglandin-F2alpha (8-iso-PGF2α) levels in Bosnian AD and VD patients and to establish whether there is an association between 8-iso-PGF2α serum concentration and cognitive impairment (CI) in patients with dementia. SUBJECTS AND METHODS Serum levels of 8-iso-PGF2α were measured by enzyme immunoassay method in AD (n=30) and VD patients (n=30) and control subjects (CG, n=30). The AD and VD group were further stratified according to the level of CI. RESULTS The serum 8-iso-PGF2α levels were significantly higher in the AD (74.00 pg/mL) and VD groups (38.00 pg/mL) compared to the CG (17.50 pg/mL). A significant difference in serum 8-iso-PGF2α levels between patients with moderate and severe CI was not established in either AD or VD. CONCLUSION Serum 8-iso-PGF2α proved to be a good biomarker in AD and VD, however it cannot be recommended for the differentiation of moderate and severe CI.

Abstract
Introduction: Poor glycemic control, assessed by higher glycated hemoglobin (HbA1c) levels, is associated with greater risk of diabetic complications. Aim: The aim of this study was to assess the association of triglyceride - to - HDL cholesterol (TG/HDL-C) ratio and triglyceride glucose (TyG) index with HbA1c and to evaluate their potential role as predictors of glycemic control in patients with diabetes mellitus type 2 (DM2). Patients and methods: This cross-sectional study was conducted in Health Center Banovici and included a total of 113 patients with DM2 classified according to their HbA1c values in two groups: DM2 HbA1c <7% - DM2 patients with good glycemic control (n=39) and DM2 HbA1c ≥7% - DM2 patients with poor glycemic control (n=74). Anthropometric, biochemical parameters and blood pressure values were measured, while TG/HDL-C ratio and TyG index were calculated. Results: TG/HDL-C ratio and TyG index were significantly higher in DM2 HbA1c≥7% compared to DM2 HbA1c<7% group (p=0.003 and p<0.001; respectively). Both TG/HDL-C ratio and TyG index were positively associated with HbA1c levels (Rho=0.29; p=0.002; Rho=0.37; p<0.001; respectively). In linear regression analysis TG/HDL-C ratio and BMI, and also TyG index and BMI were significantly independently associated with HbA1c even after controlling for age, gender, diabetes duration and smoking. When we stratified patients according to BMI values, independent association between TG/HDL-C ratio and HbA1c remained significant only in normal weight subjects (OR 0.21; 95%CI: 0.05-0.37; β=0.65; p=0.017), while independent association between TyG index and HbA1c remained significant only in overweight and obese subjects (OR 0.063; 95%CI: 0.01- 0.12; β=0.24; p =0.027). Conclusion: TG/HDL-C ratio might be a useful predictor of glycemic control in normal weight, and TyG index in overweight and obese patients with DM2.

Abstract
Objective The association between the neck circumference (NC) and components of metabolic syndrome in different countries and ethnic groups has been insufficiently investigated. The aim of the present study was to assess the impact of gender on NC values and to determine whether NC correlates with standard anthropometric measures and blood pressure values in Bosnian young adults. Materials and Methods Study participants were recruited by the snowball method. The NC, body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured by trained personnel. Differences between the means were assessed by a Student's t-test. Coefficients of correlation were determined by Pearson's test. Results In young men (n=49), the value of NC was 37.71±1.79 cm, while in young women, (n=62) the value of NC was 32.23±1.83 cm (p<0.001). A significant positive correlation in both genders between the NC and BMI (r=0.70, p<0.001 in men; r=0.53,p<0.001 in women), and between the NC and WC (r=0.48, p<0.001 in men; r=0.38, p=0.01 in women), was found. A significant correlation between the NC and SBP (r=0.08, p=0.57), and DBP (r=0.20, p=0.17), in young men was not determined. Likewise, in young women, a significant correlation between the NC and SBP (r=0.08, p=0.54), and DBP (r=0.09, p=0.49), was not observed. Conclusion Our results suggest that the NC measurement can be used as a valid method in obesity assessment in young adults. A lack of association between the NC and blood pressure requires additional investigation.

Abstract
BACKGROUND Chagas disease (CD) is a major public health concern in Latin America and a potentially serious emerging threat in non-endemic countries. Although the association between CD and cardiac abnormalities is widely reported, study design diversity, sample size and quality challenge the information, calling for its update and synthesis, which would be very useful and relevant for physicians in non-endemic countries where health care implications of CD are real and neglected. We performed to systematically review and meta-analyze population-based studies that compared prevalence of overall and specific ECG abnormalities between CD and non-CD participants in the general population. METHODS Six databases (EMBASE, Ovid Medline, Web of Science, Cochrane Central, Google Scholar and Lilacs) were searched systematically. Observational studies were included. Odds ratios (OR) were computed using random-effects model. RESULTS Forty-nine studies were selected, including 34,023(12,276 CD and 21,747 non-CD). Prevalence of overall ECG abnormalities was higher in participants with CD (40.1%; 95%CIs=39.2-41.0) compared to non-CD (24.1%; 95%CIs=23.5-24.7) (OR=2.78; 95%CIs=2.37-3.26). Among specific ECG abnormalities, prevalence of complete right bundle branch block (RBBB) (OR=4.60; 95%CIs=2.97-7.11), left anterior fascicular block (LAFB) (OR=1.60; 95%CIs=1.21-2.13), combination of complete RBBB/LAFB (OR=3.34; 95%CIs=1.76-6.35), first-degree atrioventricular block (A-V B) (OR=1.71; 95%CIs=1.25-2.33), atrial fibrillation (AF) or flutter (OR=2.11; 95%CIs=1.40-3.19) and ventricular extrasystoles (VE) (OR=1.62; 95%CIs=1.14-2.30) was higher in CD compared to non-CD participants. CONCLUSIONS This systematic review and meta-analysis provides an update and synthesis in this field. This research of observational studies indicates a significant excess in prevalence of ECG abnormalities (40.1%) related to T. cruzi infection in the general population from Chagas endemic regions, being the most common ventricular (RBBB and LAFB), and A-V B (first-degree) node conduction abnormalities as well as arrhythmias (AF or flutter and VE). Also, prevalence of ECG alterations in children was similar to that in adults and suggests earlier onset of cardiac disease.

Abstract
Background: Neck circumference (NC) is an index of subcutaneous adipose tissue distribution in an area of the upper part of the body. The aim of this study was to assess whether NC can be used as an indicator of central obesity and to determine the prevalence of central obesity in apparently healthy Bosnian young adults. Methods: Participants for this cross-sectional study were recruited using the snowball method. NC was measured in horizontal straight position by placing the top edge of a plastic tape only below the laryngeal prominence and perpendicular to the longitudinal axis of the neck, with the head positioned in the Frankfort horizontal plane. Body mass index, waist circumference (WC), and waist-to-hip ratio were taken following the WHO guidelines. Results: The study included 111 second year University of Sarajevo Dentistry students (49 students of male gender and 62 students of the female gender). Determined the optimal cutoff value of NC in the detection of central obesity based on WC values in healthy young participants of male gender was ≥37.45 cm (P < 0.001), while in healthy young participants of the female gender, it was ≥32.75 cm (P < 0.001). Based on the WHO guidelines for WC, central obesity was determined in 24.49% (n = 12) of male patients, and in 29.03% (n = 18) of female participants included in our investigation (P < 0.05). Conclusions: The results of the present study indicate that NC may be used as a screening tool for central obesity in healthy young adults. Prevalence of central obesity observed among student population suggests that there is a justified need for an implementation of healthy lifestyle programs in this population that would have preventive purposes.

Abstract
BACKGROUND The role of dietary antioxidants and plasma oxidant-antioxidant status in low-grade chronic inflammation and adipocytokine levels is not established yet. OBJECTIVES We aimed to evaluate whether total dietary antioxidant capacity (assessed by dietary ferric reducing antioxidant potential (FRAP)), serum uric acid (UA) and gamma glutamyltransferase (GGT) were associated with low-grade chronic inflammation and circulating adipocytokines. METHODS Data of 4506 participants aged ≥55years from the Rotterdam Study were analyzed. Baseline (1990-1993) FRAP score was assessed by a food frequency questionnaire. Baseline UA and GGT levels were assessed in non-fasting serum samples. Serum high sensitivity C-reactive protein (hs-CRP) was measured at baseline and 10years later. Plasma leptin, adiponectin, plasminogen activator inhibitor-1 (PAI-1) and resistin levels were assessed 10years later. RESULTS A high FRAP score was associated with lower levels of UA and GGT. Overall, no association was found between FRAP and hs-CRP levels. FRAP score was associated with lower levels of leptin and PAI-1, higher levels of adiponectin, and no difference in resistin levels. Increased levels of UA were associated with higher levels of hs-CRP, PAI-1 and leptin; lower levels of adiponectin and no difference in resistin levels. Similarly, GGT was associated with higher levels of hs-CRP whereas no association was observed between GGT and adipocytokines. CONCLUSION These findings suggest that overall antioxidant capacity of diet and low levels of UA are associated with circulating adipocytokines whereas no consistent association was found with hs-CRP.

Abstract
IMPORTANCE Epigenetic modifications of the genome, such as DNA methylation and histone modifications, have been reported to play a role in neurodegenerative diseases (ND) such as Alzheimer's disease (AD) and Parkinson's disease (PD). OBJECTIVE To systematically review studies investigating epigenetic marks in AD or PD. METHODS Eleven bibliographic databases (Embase.com, Medline (Ovid), Web-of-Science, Scopus, PubMed, Cinahl (EBSCOhost), Cochrane Central, ProQuest, Lilacs, Scielo and Google Scholar) were searched until July 11th 2016 to identify relevant articles. We included all randomized controlled trials, cohort, case-control and cross-sectional studies in humans that examined associations between epigenetic marks and ND. Two independent reviewers, with a third reviewer available for disagreements, performed the abstract and full text selection. Data was extracted using a pre-designed data collection form. RESULTS Of 6,927 searched references, 73 unique case-control studies met our inclusion criteria. Overall, 11,453 individuals were included in this systematic review (2,640 AD and 2,368 PD outcomes). There was no consistent association between global DNA methylation pattern and any ND. Studies reported epigenetic regulation of 31 genes (including cell communication, apoptosis, and neurogenesis genes in blood and brain tissue) in relation to AD and PD. Methylation at the BDNF, SORBS3 and APP genes in AD were the most consistently reported associations. Methylation of α-synuclein gene (SNCA) was also found to be associated with PD. Seven studies reported histone protein alterations in AD and PD. CONCLUSION Many studies have investigated epigenetics and ND. Further research should include larger cohort or longitudinal studies, in order to identify clinically significant epigenetic changes. Identifying relevant epigenetic changes could lead to interventional strategies in ND.

Abstract
Females have unique and additional risk factors for neurological disorders. Among classical estrogen receptors, estrogen receptor beta (ERβ) has been suggested as a therapeutic target. However, little is known about the role of ERβ in the female brain. Six electronic databases were searched for articles evaluating the role of ERβ in the female brain and the influence of age and menopause on ERβ function. After screening 3186 titles and abstracts, 49 articles were included in the review, all of which were animal studies. Of these, 19 focused on cellular signaling, 7 on neuroendocrine pathways, 8 on neurological disorders, 4 on neuroprotection and 19 on psychological and psychiatric outcomes (6 studies evaluated two or more outcomes). Our findings showed that ERβ phosphorylated and activated intracellular second messenger proteins and regulated protein expression of genes involved in neurological functions. It also promoted neurogenesis, modulated the neuroendocrine regulation of stress response, conferred neuroprotection against ischemia and inflammation, and reduced anxiety- and depression-like behaviors. Targeting ERβ may constitute a novel treatment for menopausal symptoms, including anxiety, depression, and neurological diseases. However, to establish potential therapeutic and preventive strategies targeting ERβ, future studies should be conducted in humans to further our understanding of the importance of ERβ in women's mental and cognitive health.

Abstract
Five medical databases were searched for studies that assessed the role of ERβ in the female cardiovascular system and the influence of age and menopause on ERβ functioning. Of 9472 references, 88 studies met our inclusion criteria (71 animal model experimental studies, 15 human model experimental studies and 2 population based studies). ERβ signaling was shown to possess vasodilator and antiangiogenic properties by regulating the activity of nitric oxide, altering membrane ionic permeability in vascular smooth muscle cells, inhibiting vascular smooth muscle cell migration and proliferation and by regulating adrenergic control of the arteries. Also, a possible protective effect of ERβ signaling against left ventricular hypertrophy and ischemia/reperfusion injury via genomic and non-genomic pathways was suggested in 27 studies. Moreover, 5 studies reported that the vascular effects of ERβ may be vessel specific and may differ by age and menopause status. ERβ seems to possess multiple functions in the female cardiovascular system. Further studies are needed to evaluate whether isoform-selective ERβ-ligands might contribute to cardiovascular disease prevention.

Abstract
Objectives: Aim of the present study was to investigate serum concentration of leptin and its association with values of body mass index (BMI), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) in hemodialysis (HD) patients. Methods: This cross-sectional study included 60 HD patients (34 male, 26 female) and 30 age- and sex-matched (4 males, 26 females) apparently healthy subjects. Serum leptin concentration was determined by an enzyme-linked immunosorbent assay (ELISA). Serum CRP concentration was measured by means of particle-enhanced immunonephelometry. ESR value was determined by Western Green method. BMI was calculated as weight (kg) divided by height squared (m2). Results: Results have shown that median serum leptin concentration (30.65 ng/mL; 12.48-86.40 ng/mL) was statistically significantly higher in HD patients compared to median serum leptin concentration (15.75 ng/mL; 9.15-30.65 ng/mL) in the control group of healthy subjects (p<0.05). Likewise, median serum CRP concentration (5.5 mg/L; 1.93-8.9 mg/L) and median ESR value (57.5 mm/h; 40.5-77.0 mm/h) were significantly higher in HD patients compared to median serum CRP concentration (0.8 mg/L; 0.38-1.43 mg/L) (p<0.001) and median ESR value (10.0 mm/h; 6.5-14.0 mm/h) (p<0.001) determined in the control group. Statistically significant positive correlation was found between BMI values and serum leptin concentration in HD patients (rho=0.434; p<0.001). Positive, although not significant, correlation was observed between serum CRP and leptin levels in HD patients (rho=0.171; p>0.05). Negative correlation between ESR values and serum leptin concentrations in HD patients was determined but it was not statistically significant (rho= -0.029; p>0.05). Conclusions: Increased serum concentration of leptin as pro-inflammatory cytokine as well as elevated serum values of CRP and ESR indicate presence of systemic micro inflammation in HD patients. Results of the present study point to possible use of serum leptin concentration as an indicator of nutritional status in HD patients based on observed significant positive correlation between serum leptin concentrations and BMI values. However, absence of significant association between serum leptin and CRP levels as well as between serum leptin concentrations and ESR values in HD patients requires further investigation and clarification.

Abstract
This study investigated whether serum C-reactive protein (CRP) concentration is increased in patients with type 1 diabetes mellitus with a normal body mass index (BMI) and whether BMI, glycated haemoglobin (HbA1c) and CRP are correlated in patients with type 1 diabetes. High-sensitivity CRP was determined by immunonephelometry and HbA1c by an immunoturbidimetric method in 30 patients with type 1 diabetes and 30 healthy individuals matched for age, sex and BMI. Median serum CRP concentration in patients with type 1 diabetes (1.34 mg/L) was significantly higher than healthy individuals (0.2 mg/L; p<0.0001). Positive correlation between CRP and BMI was observed (rho=0.598; p<0.0001), but no significant correlation was observed between CRP and HbA1c (rho=0.285; p=NS) in patients with type 1 diabetes. Increased CRP levels in type 1 diabetes patients do not appear to be associated with glycaemic control, and may reflect low-grade inflammation associated with atherosclerosis, as well as activation of innate immune activity.

Abstract
BACKGROUND Inadvertent intraneural injection of local anesthetics may result in neurologic injury. We hypothesized that an intraneural injection may be associated with higher injection pressures and an increase in the risk of neurologic injury. METHODS The study was conducted in accordance with the principles of laboratory animal care, and was approved by the Laboratory Animal Care and Use Committee. Fifteen dogs of mixed breed (16-21 kg) were studied. After general endotracheal anesthesia, the sciatic nerves (n= 30) were exposed bilaterally. Under direct vision, a 25-gauge, long-beveled needle (30 degrees) was placed either epineurally (n= 10) or intraneurally (n= 20), and 4 ml of preservative-free lidocaine 20 mg/ml was injected using an automated infusion pump (4 ml/min). Injection pressure data were acquired using an in-line manometer coupled to a computer via an analog-to-digital conversion board. After injection, the animals were awakened and subjected to serial neurologic examinations. One week later, the dogs were killed, the sciatic nerves excised and histologic examination was performed by pathologists blind to the purpose of the study. RESULTS All perineural injections resulted in low pressures (< or = 5 psi). In contrast, eight of 20 intraneural injections resulted in high pressures (20-38 psi) at the beginning of the injection. Twelve intraneural injections, however, resulted in pressures of less than 12 psi. Neurologic function returned to baseline within 3 h after perineural injections and within 24 h after intraneural injections, when the measured injection pressures were less than 12 psi. Neurologic deficits persisted throughout the study period after all eight intraneural injections that resulted in high injection pressures. Histologic examination of the affected nerves revealed fascicular axonolysis and cellular infiltration. CONCLUSIONS The data in our canine model of intraneural injection suggest that intraneural injections do not always lead to nerve injury. High injection pressures during intraneural injection may be indicative of intrafascicular injection and may predict the development of neurologic injury.

Abstract
BACKGROUND Unintentional intraneural injection of local anesthetics may cause mechanical injury and pressure ischemia of the nerve fascicles. One study in small animals showed that intraneural injection may be associated with higher injection pressures. However, the pressure heralding an intraneural injection and the clinical consequences of such injections remain controversial. Our hypothesis is that an intraneural injection is associated with higher pressures and an increase in the risk of neurologic injury as compared with perineural injection. METHODS Seven dogs of mixed breed (15-18 kg) were studied. After general endotracheal anesthesia, the sciatic nerves were exposed bilaterally. Under direct microscopic guidance, a 25-gauge needle was placed either perineurally (into the epineurium) or intraneurally (within the perineurium), and 4 mL of lidocaine 2% (1:250,000 epinephrine) was injected by using an automated infusion pump (4 mL/min). Injection pressure data were acquired by using an in-line manometer coupled to a computer via an analog digital conversion board. After injection, the animals were awakened and subjected to serial neurologic examinations. On the 7th day, the dogs were killed, the sciatic nerves were excised, and histologic examination was performed by pathologists blinded to the purpose of the study. RESULTS Whereas all perineural injections resulted in pressures < or =4 psi, the majority of intraneural injections were associated with high pressures (25-45 psi) at the beginning of the injection. Normal motor function returned 3 hours after all injections associated with low injection pressures (< or =11 psi), whereas persistent motor deficits were observed in all 4 animals having high injection pressures (> or =25 psi). Histologic examination showed destruction of neural architecture and degeneration of axons in all 4 sciatic nerves receiving high-pressure injections. CONCLUSIONS High injection pressures at the onset of injection may indicate an intraneural needle placement and lead to severe fascicular injury and persistent neurologic deficits. If these results are applicable to clinical practice, avoiding excessive injection pressure during nerve block administration may help to reduce the risk of neurologic injury.
